This collection investigates the multifaceted nature of American life by capturing a singular, synchronized snapshot of the nation across twenty-four hours. The project, spearheaded by Rick Smolan and David Cohen, mobilized two hundred of the world's most prominent photojournalists to document the diverse social, cultural, and geographic landscape of the United States on May 2, 1986. By utilizing a massive, coordinated effort, the authors provide a comprehensive visual record that serves as both a historical document and a study of the American experience at a specific point in the late twentieth century.

The work is regarded as a significant achievement in collaborative photojournalism, noted for its logistical ambition and the breadth of its cultural documentation. The collection serves as an essential reference for those studying the aesthetic and social preoccupations of the mid-1980s.
